in CXF 2.6.3 it is ServerWebApplicationException and in 2.7.0: WebApplicationException. ResponseExceptionMapper<WebApplicationException> will work in 2.6.3 and 2.7.0, and similarly - RuntimeException catch block will be executed

> In org.apache.cxf.jaxrs.client.ClientProxyImpl.findExceptionMapper(Method, Message)
> The responseExceptionMapper is selected based on exception defined in the resource method signature but this method may have thrown a RuntimeException :
> {code:java} 
> @Path("/")
> public interface RestMcuBoardResource {
>     @GET
>     public RestMcuBoard getBoard();
> }
> {code} 
> does not work where this one work
> {code:java} 
> @Path("/")
> public interface RestMcuBoardResource {
>     @GET
>     public RestMcuBoard getBoard() throws runtimeException;
> }
> {code}
> a fix could be :
> {code:java} 
>     private static ResponseExceptionMapper<?> findExceptionMapper(Method m, Message message) {
>         ProviderFactory pf = ProviderFactory.getInstance(message);
>         for (Class<?> exType : m.getExceptionTypes()) {
>             ResponseExceptionMapper<?> mapper = pf.createResponseExceptionMapper(exType);
>             if (mapper != null) {
>                 return mapper;
>             }
>         }
> +        return pf.createResponseExceptionMapper(RuntimeException.class);
> -        return null; 
>     }
> {code}
